Freezer paper stencils. Use sharpies or fabric markers to scribble in the design instead of fabric paint. No waiting for paint to dry, so good idea for a Brownie meeting, since they can take them home right away.
I love this sharpie marker craft - a craft idea I won't throw away! :) Possibility for Valentine's Day - make one for yourself, one for someone else. Aesthetic Nest: Craft: Scribble Initial T-Shirt (Tutorial)
